I personally think Scotland's People should flag those post-1855 death records with parents unknown.
The SP indexes are as transferred from the old printed books, which did not contain this information. SP are now adding extra information, for example mothers' maiden surnames to the deaths index and to the older births index. I personally would rather they got on with that than go back and start again with flagging up existing index entries from which one or other bit of information is missing.
You can often see that no mother's maiden surname is in the indexes because in the index the space for mmn is taken up with a row of dashes ------
Just remember that English, Welsh and Irish death certificates
never tell you the names of the parents of the deceased, and be suitably grateful to the Scottish lawmakers who decreed that both fathers' names and mothers' maiden surnames should be included by default on all types of certificate. It's only when the informant didn't know the parents' names that those spaces are left blank.
I also think the pre-1855 BMD records aren't worth 6 credits.
Some are very informative, some are not. It would be impossible for SP to go back and decide which of the pre-1855 records is worth 6 credits and which are not. Or if not absolutely impossible, very expensive and time-consuming, and there are other refinements they could make that would be much more useful.
Since the index is free, allowing one to set the number shown on one page eg. "all", 100, 200, etc., would allow people to more readily search the index for the people they want reducing chances of making a mistake.
I don't understand this. If you do a wide search you get all the matching results, with 25 index listings per page, but you can look at as many pages as you like free of charge. For example I just searched post-1855 births for M*cdonald and I got 182,522 results in 7301 pages. It's up to you to refine your search to get a manageable number of results.
Usually for post-1855 deaths one gets 3 records but sometimes just 1 or 2. Sometimes it is the other 2 random records that are the most helpful.
Are you talking about certificates now, rather than the index? The reason why you mostly get three results is that you get the whole of the page from the original book that contains the certificate you want and two that are usually unrelated.
